The document describes Freshwater Place, a mixed-use development in Melbourne consisting of two commercial office towers, a residential tower, and retail space. It details the optimization of the lighting control system at the development's first office tower, 2 Freshwater Place, by mySmart. Through reprogramming the lighting controls to reduce unnecessary lighting usage, mySmart helped 2 Freshwater Place achieve energy savings of 37% and a 4.5-star NABERS energy rating. mySmart also designed and commissioned the lighting control system for the second office tower, Twenty 8 Freshwater Place.

ABOUT THE BUILDING
Freshwater Place is an award
winning mixed use master
planned development on the
banks of the Yarra River in the
heart of Melbourne’s arts and
entertainment precinct.
Two premium grade commercial
towers and a 60 storey residential
apartment surround an urban
retail village and piazza offering
residents and office staff a vibrant
environment in which to live and
work.
PROJECT DETAILS:
FRESHWATER PLACE
2 SOUTHBANK BOULEVARDE, MELBOURNE
The first office tower to be constructed 2 Freshwater
Place, also known as 2 Southbank Boulevard, was
completed in 2005. At 55,000m2
spread over 38 levels,
2 Freshwater Place was designed for occupancy by
leading edge, high technology organisations with current
tenants including international firms Price Waterhouse
Coopers and Microsoft.
As the second stage of the development Twenty 8
Freshwater Place is a 34,000m2
, 25 level premium grade
building. The design by architect Bates Smart uses a side-
core design to provide expansive open floor plates and
extensive ESD work was undertaken in order to target a
4.5-star NABERS energy rating.
mySmart was the original C-Bus lighting control
integrator during the construction and the majority of
the tenancy fit outs at Twenty 8 Freshwater Place. Based
on our project knowledge and the quality of our service
delivery mySmart has been the exclusive provider of
C-Bus lighting controls and programming to Freshwater
Place managing agents Jones Lang LaSalle since 2009.

3. With 95% of the building leased
on its completion, 2 Freshwater
Place was occupied in 2005.
Reflecting its premium grade
positioning 2 Freshwater Place
was built to achieve the highest
energy efficiency.
Unfortunately due to operational issues the building
only achieved a 2.5-star NABERS energy rating,
well below its design capability. For Stage One of
the energy efficiency program Engineering Services
Manager, Kok Lim Ng, targeted the building’s C-Bus
lighting control system. This had been completed by
an integrator no longer in business, and Lim believed
that by reprogramming the system significant energy
savings could be made.
As a first step an audit of the building’s lighting was
undertaken. In any commercial office building there
are two main categories of lighting; tenancy office
lighting and base building lighting. Base building
lighting can be further segmented into grey areas;
plant rooms, loading docks etc. and key areas; main
foyers, lifts, lift lobbies, building perimeter and toilets.
2 FRESHWATER PLACE
OVERALL LIGHTING POWER
FOR FRESHWATER 2
Based on the successful delivery of lighting
controls at Twenty 8 Freshwater Place, mySmart
were engaged in July 2009 to act on the findings of
the audit with changes to the base building lighting
control strategy at 2 Freshwater Place.
The reprogramming by mySmart included;
• Aligning the building operation and after-hours
schedules
• Rescheduling the grey areas to the lowest
possible operational hours
• Reprogramming key areas to make use of natural
light
• Using sensors to shut down key area lighting
when not required
• Ensuring all lighting is shut down when a floor is
unoccupied after hours
By September the optimised lighting control strategy
at 2 Freshwater Place had reduced consumption
by 18,400kWh, a saving of 7.7% over the pre-audit
monthly figures.
Over the period from July 2008 to July 2014 the
optimisation of the lighting control strategy, along
with a lamp replacement program in Stage Three, has
reduced the lighting energy consumption by 37%.
Further since January 2011, 2 Freshwater Place has
consistently gained a 4.5-Star NABERS energy rating.
STAGE ONE
The nature of the strategy for stage one is aggressive.
Wherever possible lighting is turned off to reduce
energy consumption. This is achieved through
programming and lights are either permanently
switched off or the amount of time they are on is
drastically reduced.
STAGE TWO
After 18 months, feedback from the buildings
occupants was used to determine which of the
disabled lighting should be turned back on. An
investment in more sophisticated programming is
required to deliver the lighting levels requested by
occupants whilst still keeping energy consumption
below that recorded at the start of Stage One.
Energy consumption in Stage Two will increase over
that recorded at the end of Stage One however
savings made in Stage One can be used to offset the
increased cost.
STAGE THREE
At the end of Stage Two the majority of savings
possible from programming will have been made.
Other options including upgrading of lamps are now
implemented while programming changes for final
areas including carparks are undertaken.
TWENTY 8 FRESHWATER PLACE
mySmart were instrumental in the delivery of Twenty 8 Freshwater
Place’s lighting system, designing and commissioning the base
building and all bar one tenancy area control systems. Initially
Twenty 8 Freshwater Place was designed as a 4.5-star NABERS
energy rated building. Since completion of the base building,
mySmart has been working with Jones Lang LaSalle to optimise
the entire building to ensure a NABERS energy rating of 5 stars is
achieved.
What is more, is that both 2 and Twenty 8 Freshwater Place have
gained their 4.5 and 5-Star NABERS energy ratings unassisted, i.e.
zero percent Green Power.

FROM THE ENGINEERING
SERVICES MANAGER
Kok Lim Ng is the Engineering
Services Manager for Jones Lang
Lasalle at Freshwater Place.
Recognising that there were
some significant issues in the
operation of 2 Freshwater Place,
Lim set to work to try and turn the
building’s performance around.
THE STRATEGY
Lim’s first call was to measure and asses the building’s
energy usage. By conducting an audit Lim was able to
determine exactly how and where energy was being
used. “The first goal must be to establish a baseline
for energy usage”, says Lim. “After that you can work
to isolate seasonal and daily variances that impact on
performance.”
INVEST TO RETURN
Many in our industry find it can be hard to ask owners to
invest in returns they feel may not benefit them directly.
Lim’s initial approach was to look for operational
savings in order to create surplus funds. Once funds
were available they were used where they will give the
quickest returns from the smallest investment.
Optimising lighting automation and control is often the
quickest method to get a quick return. “With mySmart
charging an hourly rate many changes can be made in
a very short period of time for not a lot of money.” says
Lim. “The critical factor is that the integrator is suitably
experienced and able to quickly understand what
changes are required and how best to implement them.”
NOTHING IS IN ISOLATION
Another point to consider is that no change acts in
isolation. A simple change in the programming of the
lighting leads to a reduction of energy used and also
of heat generated. A reduction of heat generated by
lighting also reduces the load on the air-conditioning.
A reduction in the air-conditioning load reduces the
baseline energy and water consumption.”While these
reductions may not be huge, it is a constant loop of
analysis, change, more analysis and more change that
leads to a fully optimised building.”
